A/n: This one is just TNT's idea. Another one with Trader Johan - I'm starting to get the idea that you just like watching him mess things up!

EDIT: That's it, folks! No more requests. I'm booked up till chapter 74, and 75 is going to be one of my own design. Sorry!

'Can't we just get a different trader?'

"No." Hiccup responded. "Johan's the best, and he's actually the fairest, though he might not look like it. Besides, he promised not to bring any parrots."

'Like he 'promised' last time?' Toothless asked disbelievingly.

"It's different this time." Hiccup promised. "Parrots are banned; he wouldn't go against Berk law."

'Still can't believe you did that,' Toothless laughed. 'absolutely amazing..."

Hiccup sighed. "Sure, it was funny," he admitted. "but it was a perfectly good reaction at the time. And we haven't had any trouble with them since, have we?"

'No,' Toothless conceded, 'but there was the terrible terror thing.'

"That's different." Hiccup argued. "Besides, it's beside the point. We're going to be watching Johan the whole time. It'll be fine."

'Great. Now you jinxed it.'

"Shut up."

Hiccup and Toothless landed on Johan's boat before it landed, ignoring his grandiose tales of adventure while they seached it for anything potentially harmful.

"Err, Johan?" Hiccup said slowly, peeling the cloth covering from one of the containers. "What's this?"

"What, Hiccup?" Johan was pulled from recounting the tale of how he managed to get the fleece he was wearing to look over at the Viking. "Ah, yes, that's an eel." he said proudly.

It was the wrong thing to say. "Do you remember the effect eels have on dragons?" Hiccup asked dangerously. At the mention of eels, Toothless had retreated to the opposite side of the boat, hissing at the offending container.

"Well, yes, but it's a very special eel."

"Special?" Hiccup repeated, not totally won over but no longer mad.

"Yes!" Johan said hurriedly. "It can shoot lightning!"

"A lightning eel?" As amazing as that sounded, it only made them more dangerous. "Well, as long as you keep it out of sight and contained..."

"Oh, thank you Hiccup!" Johan beamed. "I'll make sure no one ever knows it's here!"

Of course, someone ended up buying it. It's just my luck, Hiccup thought miserably, scowling over at Fishlegs.

"What?" the other Viking said defensively, "It's so interesting! Look at the way it crackles with lightning! Amazing!"

"Yes, amazing." Hiccup repeated, nowhere near as enthusiastically. "And I'd prefer it an amazingly large distance from here."

'I'm with Hiccup here,' Meatlug admitted, eyeing the eel warily. 'What if someone accidentally eats it? Who knows what it'll do?'

"Oh, that'll ne -"

"Don't finish that sentence." Hiccup warned, hand pressed against Fishlegs' mouth. "Even thinking it is jinxing it."

Fishlegs pouted, but didn't argue back. "Fine. I'm being careful though, see?"

Hiccup nodded. "Just don't let it out of your sight."

The twins stared at the container.

"What do you think's in it?" Tuffnut wondered.

"A dragon?" Ruffnut guessed. "Whatever it is, Hiccup said it was dangerous..."

"Let's let it out!"

"Yeah!"

The twins jumped down from their hiding spot on top of Fishlegs' house, rushing up behind him. The thing in the tank was identifiable as some sort of fish from this distance. Tuffnut tapped Fishlegs on the back while Ruffnut ran around him.

"What are you doing?" Fishlegs asked, a mix of suspicion and nervousness in his tone; he'd fallen victim to the twins' pranks far too many times to not recognise the look of mischief.

"Nothing." Tuffnut said unconvincingly, looking round Fishlegs to see how far Ruffnut had got with freeing the fish - an eel, actually, as it turned out.

"Where's Ruffnut?" Fishlegs wondered. A pause. "Wait." He turned round to see the other twin, caught in the act of shuffling the eel's tank along. "No, you can't have that!"

The twins looked at each other, grabbed the tank and ran.

"Hiccup!"

Hiccup perked up at the cry of his name. It was Fishlegs' voice, and it sounded urgent.

The eel. he realised, jumping into action and running off in the direction of the shout.

"Curse you Johan!"

When Hiccup finally reached Fishlegs, the tank was nowhere to be found. And neither were the twins.

"What happened?" he demanded.

Fishlegs shrank back under his glare. "They grabbed the tank and ran." he explained nervously. "I couldn't stop them - they were too fast."

Hiccup sighed, dragging a hand down his face. "Of course this would happen," he muttered, "why would it go right?"

"Fine." A deep breath later, he was back to normal. "Let's get the twins before they can cause any more damage."

The twins were on the beach, and, amazingly, they weren't trying to feed the eel to anyone.

"Be free!" Ruffnut yelled, chucking the eel and all the water surrounding it into the sea.

Fishlegs whimpered as he watched his eel swim away, thinking of the hammer he'd had to trade to get it. "What was that for?"

"Hiccup said it was dangerous." Ruffnut explained. "So if we let it go, it'll destroy stuff!"

Hiccup laughed. "Well, that's one way of thinking about it." Luckily, not the right way... "Sorry Fishlegs," Hiccup said unapologetically, "I did say not to let it out of your sight."
